Is 480p the same as 640x480 @ 60hz

Like it says, is it?

I'm trying to figure out if I can run my xbox through a monitor (NTSC xbox component output through x2vga to Asus vw222u) at 480p so I'm not limited to the handful of games that support 720p.

E.E.

480p is 854 x 480, 640 x 480 is.... not the same.

Now I'm really confused. The info from here would suggest otherwise and matches up with what I'm reading elsewhere as well.

The way I've been reading it so far, gives me 480p is 640x480 or 720x480 with square pixels. Which I should say means nothing to me.

Check out the Widescreen resolution Fact Sheet

854 / 16 = 53.375

53.375 * 9 = 480.375

I couldn't have put it better myself.

That's interesting. Does that mean that 480p only relates to widescreen formats? I thought the aspect ratio had nothing to do with it.

Well, the ATSC standard says that 480p can be 704x480 or 640x480 according to Wikipedia. But I think the 704x480 might be a typo.

That's at 24 or 30hz.

The standard at 60hz for Enhanced Digital Television is 720x480 active pixels.

This is all wikipedia crap, but for true 16:9 it should be 854x480. The only thing I've ever seen use 480p is my Wii.

I hear what you're saying but I just don't get the connection to 16:9 aspect ratio widescreen format. I thought the question was purely about 480p which as far as I'm aware has nothing to do with aspect ratio. Perhaps there's something here I missed?

854x480 is the typical native resolution of an SD 16:9 digital screen. But it's not the resolution of a typical 480p ED component video signal, and is not what the Xbox 360 will output over component if it's playing by the rules. It should be 720x480.

Anyway, it doesn't matter much. I had no idea what an x2vga was, but I just Googled it - I don't think you will have anything to worry about so long as the Xbox outputs a genuine 480p component video signal. Xbox->480p->x2vga->monitor should work.

I'm still trying to get my head around this one. But I will hopefully be able to shift the Xbox to 480p this afternoon, and I suppose I will find out then.
